I have scoured the docs and I can't seem to find any indication if I can access the category selector seen in many of the stock Roku screens and create one in my custom roScreen. Is this possible at all?
Additionally, it appears that other than the video player, that there are no other UI widgets that can be used with a custom roScreen. Am I missing something fundamental here? I've started to roll my own concept of labels, buttons, tables, etc. but it seems like this is quite an investment in building my own UI toolkit when I would hope this would be part of the stock SDK. Am I just mistaken?
You are right. roScreen is a separate screen that in general cannot be used underneath other *Screen* objects and there are no "parts" that can be assembled and used on an roScreen. You would have to create usable parts separately. roScreen is designed mostly for custom UI where you want fine control of the UI and/or better performance of drawing (using direct drawing, double buffering, etc.) with the drawback of the developer needing to write a lot of supporting code.
I have used many of the selector screens in a stack for basic selection, then instantiated an roScreen on top for the "main" application/screen functionality, then deleted to roScreen when done to reveal the *Screen* stack again. Works well, but a little tricky. The use of roScreen relative to other objects is decribed in a forum post.
MSGreg, thanks for the response. I was afraid that I was correct. Seems very limiting and hard to bootstrap but I've gotten pretty far in a few days. Your thread link was very helpful as well since I needed to do something similar in my channel. Thanks.
@Joel - Unfortunately no...we're doing a very custom high end channel for a customer. They don't want stock anything. @TheEndless - Thanks, I know how to use the filters in the poster screen. My hope was that it could be used as a standalone component in a roScreen.

You really should start your own thread vs piggybacking on a thread not directly relevant to your question, and of course you need to specify exactly which type of screen you would use to display the banner ad. Before you do, search the forum to see if the answer might already be here.
